Well back then there was no intrusive service for me no kissing and oral was with a condom so even though he was very old i got through it as it was not overly intimate.

Same , 90s,  couldn't get hard but could still come...penises are strange..at that age anyway! I've had loads between 80-90 and some can get hard, some can't, they're all so different,  obviously I imagine some are using viagra beforehand but as far as I know that doesn't increase the ability to climax, just increases bloodflow/ability to get hard

Mirian were you blessed during the service ?
